oracle.toplink.essentials.internal.ejb.cmp3.EntityManagerSetupImpl.predeploy()

Perform any steps necessary prior to actual deployment. This includes any steps in the session creation that do not require the real loaded domain classes. The first call to this method caches persistenceUnitInfo which is reused in the following calls. Note that in JSE case factoryCount is NOT incremented on the very first call (by JavaSECMPInitializer.callPredeploy, typically in preMain). That provides 1 to 1 correspondence between factoryCount and the number of open factories. In case factoryCount > 0 the method just increments factoryCount. factory == 0 triggers creation of a new session. This method and undeploy - the only methods altering factoryCount - should be synchronized. @return A transformer (which may be null) that should be plugged into the properclassloader to allow classes to be transformed as they get loaded. @see #predeploy(javax.persistence.spi.PersistenceUnitInfo,java.util.Map)

                    persistenceInfo.setNewTempClassLoader(JavaSECMPInitializer.getMainLoader());
                }
            }
            // call predeploy
            // this will just increment the factory count since we should already be deployed
            emSetupImpl.predeploy(emSetupImpl.getPersistenceUnitInfo(), nonNullProperties);
        }
        
        EntityManagerFactoryImpl factory = null;
        try {
            factory = new EntityManagerFactoryImpl(emSetupImpl, nonNullProperties);

            }
        }
        
        ClassTransformer transformer = null;
        if(!emSetupImpl.isDeployed()) {
            transformer = emSetupImpl.predeploy(info, nonNullProperties);
        }
        if (transformer != null){
            info.addTransformer(transformer);
        }
        // When EntityManagerFactory is created, the session is only partially created

            }
            // Make the callback
            AbstractSessionLog.getLog().log(SessionLog.FINER, "cmp_init_invoke_predeploy", persistenceUnitInfo.getPersistenceUnitName());


            // A call to predeploy will partially build the session we will use
            final ClassTransformer transformer = emSetupImpl.predeploy(persistenceUnitInfo, mergedProperties);
    
            // If we got a transformer then register it 
            if ((transformer != null) && (globalInstrumentation != null)) {
                AbstractSessionLog.getLog().log(SessionLog.FINER, "cmp_init_register_transformer", persistenceUnitInfo.getPersistenceUnitName());
                globalInstrumentation.addTransformer(new ClassFileTransformer(){
